Über MPG-DateienVorteilsvergleich
MP3 Vorteile
- Universal support — every device, every player, every car stereo.
- Small file sizes with acceptable quality at 128–320 kbps.
- Completely royalty-free since April 2017.
- ID3 metadata tags support artist, album, cover art, lyrics, and more.
- Efficient decoding — runs on the most basic hardware.
MPG Vorteile

- Trivially rewrappable to .mp4 without re-encoding.
- Low decoding overhead.
Einschränkungen
MP3 Einschränkungen
- Lossy — re-encoding compounds quality loss.
- Outperformed by AAC, Opus, and OGG at equivalent bitrates.
- Pre-echo artifacts on sharp percussive sounds.
- No native support for multichannel audio (only stereo).
- Bitrate capped at 320 kbps.
MPG Einschränkungen
- Aging codec — larger files than modern alternatives.
- No HDR, no modern audio, no modern subtitles.
- Mostly legacy — not used for new production.
